Description

엘리베이터용 합성섬유 로프{SYNTHETIC FIBER ROPE FOR ELEVATORS}Synthetic fiber rope for elevator {SYNTHETIC FIBER ROPE FOR ELEVATORS}

종래로부터, 엘리베이터의 카를 매달은 주삭(主索)으로 와이어로프 즉 철강제로프가 사용되고 있다, 또 엘리베이터에서 정전등에 의해 카가 불시에 정지한 경우, 카에 갇힌 승객을 구출할때 승강로에서의 카의 불시정지위치를 특정한 후 구출작업이 진행된다.Conventionally, wire ropes or steel ropes have been used as the main suspensions for hanging cars of elevators, and when cars are accidentally stopped by blackouts in elevators, the cars in the hoistway when rescued passengers trapped in cars After specifying the stop position, the rescue operation proceeds.

이와 같은 승객의 구출작업에 대비해서, 주삭에 승강로에서의 카위치에 대응한 지표가 미리 설정된다. 그리고 카의 불시정지시에 주삭에 설치된 지표를 통해서 카의 불시정지위치를 특정 예를 들면 승강로의 5층과 6층을 그 사이로 특정해서 승객의 구출작업이 진행된다.In preparation for such a rescue operation of passengers, an index corresponding to the car position in the hoistway is set in advance. In addition, the emergency stop position of the car is specified through the indices installed on the main body during the sudden stop of the car, for example, the fifth and sixth floors of the hoistway, and the rescue operation of the passenger proceeds.

이 같은 승객의 구출작업을 위해, 엘리베이터의 설치후에 와이어로프로된 주삭에 대해 적당한 도료에 의해 전술한 지표가 설치된다.For such a rescue operation of the passenger, the above-mentioned indicators are provided by a suitable paint for the wire rope-grinding after installation of the elevator.

이 때문에, 장기간의 엘리베이터의 사용에 의해 로프유(油)에 의한 오손이나, 주삭의 손모에 의한 도료의 탈락등에 의해 지표가 식별곤란하게 된다. 이 때문에, 불시정지시의 카내 승객의 구출작업에 지장이 생긴다는 문제점이 있었다.For this reason, the use of an elevator for a long time causes the index to be difficult to distinguish due to fouling caused by rope oil or paint falling off due to the wear and tear of grinding. For this reason, there was a problem in that a rescue operation of the passenger in the car during the uninterrupted interruption occurred.

따라서 본 발명은, 주삭에 설치된 지표가 주삭을 매달은 공사후에도 쉽게 식별할 수 있는 엘리베이터용 합성섬유 로프를 얻는 것을 목적으로 한다.Therefore, an object of the present invention is to obtain a synthetic fiber rope for an elevator that can be easily identified even after construction in which the indicators provided on the main suspension are suspended.

(발명의 개시)(Initiation of invention)

본 발명은 엘리베이터용 합성섬유 로프로된 주삭의 외주측을 구성하는 다수의 가는줄에 가요성 합성수지로 되고 가는줄 외주에 덮어서 형성되고 또 소정길이 구간마다에 인접한 다른 구간과는 이색을 이루는 외장피복층을 피복한다. 그리고 외장피복층의 하나의 착색구간에 의해, 그 착색구간과 주삭이 감겨진 활차와의 관계에 따라 승강로에서의 카의 위치를 미리 설정한다. 이로 인해 주삭에 설치된 지표의 기능을 얻을 수가 있다.The present invention is made of a flexible synthetic resin on a plurality of thin lines constituting the outer peripheral side of the injection made of synthetic fiber rope for elevators and is formed by covering the thin line outer periphery and is different from other sections adjacent to each predetermined length section To cover. Then, by one colored section of the exterior coating layer, the position of the car in the hoistway is set in advance in accordance with the relationship between the colored section and the pulley on which the main wheel is wound. This makes it possible to obtain the function of the indicator installed on the main grinding.

또 외장피복층이 합성수지제이므로 합성섬유 로프의 제조단계에서 쉽게 착색할 수가 있고 장기간의 엘리베이터의 사용후라도 외장피복층의 손모등에 의해 식별곤란하게 되는 불편을 방지할 수가 있다. 따라서, 불시정지시의 카내 승객의 구출작업에 적절하게 대응할 수가 있어 구출작업을 신속화 할 수가 있다.In addition, since the outer coating layer is made of synthetic resin, it can be easily colored in the manufacturing stage of the synthetic fiber rope, and it is possible to prevent inconvenience that can be difficult to distinguish due to wear and tear of the outer coating layer even after long-term use of the elevator. Therefore, it is possible to appropriately cope with the rescue operation of the passenger in the car at the time of non-stop, and the rescue operation can be speeded up.

또 본 발명은 외장피복층을 작은줄의 색과는 다른색으로 해서 외장피복층의 손모상태의 판정을 용이하게 하고 적절화 할 수가 있다.In addition, the present invention can make the exterior coating layer different from the color of the small lines to facilitate and appropriately determine the state of wear of the exterior coating layer.

이 때문에, 엘리베이터의 주삭의 보수점검 작업능률을 향상시킬 수가 있다.For this reason, it is possible to improve the work efficiency for maintenance inspection of the injection of the elevator.

또 본 발명은 상기 작은줄의 표면에 상기 외장피복층과 다른 색의 도료층을형성하는 것으로 해도 된다.In addition, the present invention may form a coating layer of a different color from the exterior coating layer on the surface of the small cord.

또 본 발명은 중심철선과 다수의 가요성 함성섬유가 함께 꼬여져서 되고, 상기 중심철선의 외주에 배치된 다수의 작은줄과 가요성 합성수지로 되고 상기 가는줄의 외주를 덮고 형성된 외장피복층을 구비하고, 상기 작은줄의 표면에는 상기 외장피복층과 다른색의 도료층이 형성되어 있는 엘리베이터용 합성섬유 로프로 해도 된다.In another aspect, the present invention is the core iron wire and a plurality of flexible constituent fibers are twisted together, a plurality of small wires and flexible synthetic resin disposed on the outer periphery of the center wire and provided with an outer coating layer formed covering the outer periphery of the thin wire In addition, it is good also as an elevator synthetic fiber rope in which the coating layer of the color different from the said exterior coating layer is formed in the surface of the said small file | line.

또 본 발명은 상기 도료층을 형광도료의 층으로 해도 된다.In the present invention, the coating layer may be a layer of fluorescent paint.

본 발명은, 활차에 감겨져 승강체를 매달고, 활차의 회전에 의해 구동되어 승강체를 승강시키는 엘리베이터용 합성섬유 로프에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an synthetic fiber rope for an elevator that is wound on a pulley to suspend a lifting body and is driven by the rotation of the pulley to lift the lifting body.

도 1은 본 발명에 관한 바람직한 엘리베이터용 합성섬유 로프의 횡단면도.1 is a cross-sectional view of a preferred synthetic rope for the elevator of the present invention.

도 2는 도 1에 표시하는 합성섬유 로프의 사시도.2 is a perspective view of a synthetic fiber rope shown in FIG.

(발명을 실시하기 위한 최량의 형태)(The best form to carry out invention)

본 발명의 실시의 형태를 보다 상세하게 설명하기 위해, 첨부한 도면에 따라 이를 설명한다. 즉 도 1 및 도 2에서, 1은 합성섬유 로프의 횡단면에서의 중심부에 배치된 중심강선이고, 각각 다수의 합성섬유가 꼬아져서 된 작은줄의 여러개가 꼬아져서 구성되어 있다.EMBODIMENT OF THE INVENTION In order to demonstrate embodiment of this invention in detail, it demonstrates according to attached drawing. That is, in Figs. 1 and 2, 1 is a central steel wire disposed at the center in the cross section of the synthetic fiber rope, and is composed of a plurality of twisted small strings each of which a plurality of synthetic fibers are twisted.

2는 중심강선(1)의 외주에 배치된 다수의 작은줄로 각각 다수의 가요성 합성섬유가 꼬여져서 구성되어 있다.2 is a plurality of small lines arranged on the outer periphery of the central steel wire (1), each composed of a plurality of twisted flexible fibers.

3은 외장피복층으로 가요성 합성수지로 되고 작은줄(2)의 외주를 덮고 형성된다. 4는 외장피복층(3)의 소정길이에 의해 형성된 제1구간, 5는 제1구간(4)에인접해서 형성되어 제1구간(3)과는 이색을 이루는 제2구간, 6은 제2구간(5)에 인접해서 형성되어 제2구간(5)과는 이색을 이루는 제3구간, 7은 제3구간(6)에 인접해 형성되어 제3구간(6)과는 다른색을 이루는 제4구간이다.3 is an outer covering layer, which is made of a flexible synthetic resin and covers the outer circumference of the small string 2. 4 is a first section formed by a predetermined length of the exterior coating layer 3, 5 is a second section formed adjacent to the first section 4 to be different from the first section 3, and 6 is a second section. A third section formed adjacent to (5) and having a different color from the second section (5), and a fourth section formed adjacent to the third section (6) to form a different color from the third section (6) It is a section.

또, 외장피복층(3)의 길이에서의 다른 구간에서도, 소정길이구간마다에 인접한 다른 구간과는 이색의 구간이 형성되어 있다.In addition, in the other sections in the length of the exterior coating layer 3, sections different from the other sections adjacent to each of the predetermined length sections are formed.

또, 외장피복층(3)은 작은줄(2)의 색과는 이색으로 제작되어 있다.The outer coating layer 3 is made of a different color from the color of the small string 2.

상기와 같이 구성된 엘리베이터용 합성섬유 로프에서, 작은줄(2)은 합성섬유제이고, 또 외장피복층(3)은 가요성 합성수지제이므로, 제조단계에서 각각 적당한 색으로 쉽게 착색할 수가 있다. 그리고 외장피복층의 하나의 착색구간에 의해, 그 착색구간에 의해 그 착색구간과 주삭이 감겨진 활차(도시하지 않음)와의 관계에 따라 승강로(도시하지 않음)에서의 카(도시않음)의 위치를 미리 설정한다. 이로써, 함성섬유 로프에 설치된 지표의 기능을 얻을 수가 있다.In the synthetic fiber rope for elevators configured as described above, since the small string 2 is made of synthetic fiber and the outer covering layer 3 is made of flexible synthetic resin, each color can be easily colored in a suitable color in the manufacturing step. The position of the car (not shown) in the hoistway (not shown) is determined by one colored section of the exterior coating layer and a relationship between the colored section and the pulley (not shown) wound around the colored section. Set in advance. As a result, the function of the indicator provided on the woven fiber rope can be obtained.

이러한 구성에 의해 장기간의 엘리베이터 사용후라도 오손등에 의해 지표가 식별곤란하게 되는 불편함을 방지할 수가 있다.This configuration prevents inconvenience that the indicators become difficult to distinguish due to fouling or the like even after long-term use of the elevator.

따라서 불시의 정지시의 카내 승객의 구출작업에 적절하게 대응할 수가 있어 구출작업을 신속화할 수가 있다.Therefore, it is possible to appropriately cope with the rescue operation of the passenger in the car at the time of the unexpected stop, and the rescue operation can be speeded up.

또, 착색구간에 의해 합성섬유 로프의 경년적인 신장량을 쉽게 판정할 수가 있고, 엘리베이터의 주삭의 보수점검 작업능률을 향상시킬 수가 있다.In addition, the coloring section makes it possible to easily determine the amount of elongation of the synthetic fiber rope and improve the work efficiency of maintenance inspection of the elevator's main grinding.

또 외장피복층(3)이 작은줄(2)의 색과는 다른색으로 제작되어 있으므로, 외장피복층(3)손모상태를 쉽게 적절하게 판정할 수가 있다. 이 때문에 엘리베이터의주삭의 보수점검 작업능률을 향상할 수가 있다.In addition, since the exterior coating layer 3 is made of a color different from the color of the small string 2, it is possible to easily and appropriately determine the state of the exterior coating layer 3 being damaged. For this reason, the maintenance efficiency of the maintenance of the grinding of an elevator can be improved.

또 작은줄(2)의 표면에 도료를 함침시켜서, 도료층을 형성시킨다. 이로 인해, 외장피복층(3)이 마모해서 소실상태가 되었을때에 작은줄(2)의 도료가 합성섬유 로프를 감은 활차(도시않음)에 전사된다. 이와 같이 구성함으로써, 엘리베이터의 정기검사를 실시할때, 엘리베이터용 합성수지 로프전체를 관찰해서 작은줄(2)이 보이는 곳이 있는지의 여부를 눈으로 조사하지 않아도 활차에 작은줄(2)의 도료가 전사되어 있는지 관찰하는 것만으로 외장피복층(3)의 손모를 적절하게 판단할 수 있고, 엘리베이터 주삭의 보수점검 작업능률을 향상할 수가 있다. 또 작은줄(2)의 표면에 형성하는 도료층은 형광도료의 층인것이 바람직하다.Further, the surface of the small string 2 is impregnated with a paint to form a paint layer. For this reason, when the exterior coating layer 3 wears out and disappears, the paint of the small string 2 is transferred to the pulley (not shown) which wound the synthetic fiber rope. In this way, when performing regular inspection of the elevator, the paint of the small rope 2 is applied to the pulley without observing the entire synthetic resin rope for the elevator and visually checking whether the small wire 2 is visible. Only by observing whether the transfer is carried out, the wear and tear of the exterior coating layer 3 can be judged appropriately, and the work efficiency of maintenance inspection of elevator grinding can be improved. Moreover, it is preferable that the coating layer formed on the surface of the small file | line 2 is a layer of fluorescent paint.

형광도료의 층이면 그 형광특성에 이해 점검작업자의 눈에 띄이기 쉬우므로, 활차에 전사된 경우에 간단하게 도료를 검출할 수 있다. 또 한번 활차에 전사된 형광도료는 떨어지기 어려우므로, 정기점검의 시기가 다소 늦어져도, 도료의 검출은 쉬운 것이다.If it is a layer of fluorescent paint, it is easy to grasp the fluorescence characteristic of the inspection worker, and therefore, the paint can be easily detected when transferred to the pulley. Since the fluorescent paint transferred to the pulley once again is hard to fall off, the detection of the paint is easy even if the periodical inspection is somewhat late.

이상과 같이 본 발명에 관한 엘리베이터용 합성섬유 로프는 엘리베이터용 함성섬유 로프로된 주삭의 외주측을 구성하는 다수의 작은줄에 가요성 합성수지로 되고 작은줄의 외주에 덮어서 형성되고, 또 소정길이 구간마다에 인접한 다른 구간과는 이색을 나타내는 외장피복층을 피복한 것이다.As described above, the synthetic fiber rope for an elevator according to the present invention is formed of a flexible synthetic resin on a plurality of small lines constituting the outer circumferential side of the main body made of a synthetic fiber rope for an elevator, and is formed by covering the outer circumference of the small line, and a predetermined length section. It is covered with an outer coating layer showing a different color from other sections adjacent to each.

그리고 외장피복층의 하나의 착색구간에 의해, 그 착색구간과 주삭이 걸려있는 활차와의 관계에 따라 승강로에서의 카의 위치를 미리 설정한다. 이로써, 합성섬유 로프에 설치된 지표의 기능을 얻을 수가 있다.Then, by one colored section of the exterior coating layer, the position of the car in the hoistway is set in advance in accordance with the relation between the colored section and the pulley on which the grinding is applied. Thereby, the function of the indicator provided in the synthetic fiber rope can be obtained.

이로 인해, 장기간의 엘리베이터의 사용후라도 오손에 의해 지표가 식별곤란하게 되는 불편을 방지할 수가 있다.For this reason, it is possible to prevent inconvenience that the indicator becomes difficult to distinguish due to fouling even after long-term use of the elevator.

이 때문에, 불시에 정지하였을때의 카내 승객의 구출작업에 적절하게 대응할 수 있어서 구출작업을 신속화 할 수가 있다.For this reason, it is possible to appropriately cope with the rescue operation of the passengers in the car when the vehicle is stopped at an unexpected time, thereby speeding up the rescue operation.

따라서, 활차에 감겨서 승강체를 매달은 엘리베이터용 합성섬유 로프로 유용하고, 또 활차의 회전에 의해 구동되어 승강체를 승강시키는데 적당하다.Therefore, it is useful as a synthetic fiber rope for an elevator wound around a pulley and suspended by a pulley, and is also suitable for driving a lift by lifting the pulley.

또 본 발명에 관한 엘리베이터용 합성섬유 로프는 작은줄의 색과는 외장피막층의 색을 다르게 제작해서 외장피막층의 손모상태의 판정을 쉽게 하고 적절화시킨 것이다.In addition, the synthetic fiber rope for an elevator according to the present invention is manufactured by making the color of the outer coating layer different from the color of the small string to facilitate and appropriately determine the state of wear of the outer coating layer.

이 때문에 활차에 감겨서 승강체를 매달은 엘리베이터용 합성섬유 로프로서 유용하고 또 활차의 회전에 의해 구동되어 승강체를 승강시키는데 적합하다.For this reason, it is useful as a synthetic fiber rope for elevators that are wound around a pulley and suspended by a pulley, and are driven by the rotation of the pulley to be suitable for lifting the lift.
